CVE-2024-56724

  3. CVE-2024-56724
In the Linux kernel, the following vulnerability has been resolved: mfd: intel_soc_pmic_bxtwc: Use IRQ domain for TMU device While design wise the idea of converting the driver to use the hierarchy of the IRQ chips is correct, the implementation has (inherited) flaws. This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ). Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mfd: intel_soc_pmic_bxtwc: Use IRQ domain for TMU device Si bien en términos de diseño la idea de convertir el controlador para usar la jerarquía de los chips IRQ es correcta, la implementación tiene fallas (heredadas). Esto se reveló cuando platform_get_irq() había iniciado WARN() en IRQ 0, que se supone que es un número IRQ de Linux (también conocido como vIRQ). Reelabore el controlador para respetar el dominio IRQ al crear cada dispositivo MFD por separado, ya que el dominio no es el mismo para todos ellos.
